Remove the compat shims for the ISA old-stlye in{b,w,l}()/out{b,w,l}()
and friends along with all hacks required to implement them. None of
the drivers currently built (as part of GENERIC, LINT or modules) on
sparc64 or sun4v and none of those we might want to use there in
future uses them, AFAICT there actually never was a driver hooked up
to the sparc64 or sun4v build that correctly used these functions
(and it looks like that due to a bug read{b,w,l}()/write{b,w,l}() and
the other functions working on a memory handle never actually worked on
sun4v). All they ever were good for on sparc64 and sun4v was erroneously
dragging in dependencies on isa(4) in drivers like f.e. dpt(4), si(4)
and syscons(4) in source files that supposedly were bus-neutral and
hiding issues with drivers like f.e. ng_bt3c(4) that used these
functions with busses other than isa(4) and therefore couldn't work on
these platforms.
